Never made this mistake in my life before, but my wheel suddenly felt funny when I decided to hammer up an incline on my ride today.

Turns out that the QR wasn't tight enough and the drive side partially pulled out of the rear drops. Thankfully, my guads weren't too big because my bike is fine...

Lucky.....could have been painful!!

Luckily you hadn't filed down the rear lawyer lips....

My frame started making creaky sounds over the weekend while on a climb. Somewhere in the rear, so I suspect I may have zit building. I'll look into it before my next ride and squeeze away any possibility of the rear wheel popping out when my guads dial it up to 400.

Really guys?

Welcome to BF. You have just achieved the sincerest form of flattery.

If you can become part of the lingo after only 1 thread you've got real potential.

My QR really did slip today and partially let out the rear wheel causing it to jam. I was using the POS skewer that came with my trainer and it is harder to tighten properly than any other I've used. This is the first time I've made that mistake.

Now that I reflect on my experience, I realize that it is more likely that I got off easy because my rear stays are CF rather than steel...

you are lucky -- they could have kersploded killing everyone

Notice there's no pictures. Did you shave your legs and were too embarrassed to show them?

On a more serious note, the late Sheldon was very big on making sure quick releases were good quality. He has some explanations on the website.

One of the issues I had on a steel frame that had done many thousands of kilometres was the acorn nut had worn grooves into the dropout surface, so it wasn't biting as well as it should. I ended up slipping the rear wheel frequently until I got a new QR that got me through the 1200 I was about to ride. I think I ended up filing the surface down flat again.

Maybe if the rear dropout is CF/aluminium, there might be bite-in issues with the acorn nut's serrations.

My friend's front QR came off one day on his downhill mountain bike.....






......while he was going downhill. It looked painful...

Legs are shaved, but I wasn't carrying a camera or my cell. Even if I had been, I didn't have time to do photoshop work to correct guad size distortion from "inaccurate" rendition by the cheap circuitry these devices contain...

As evidence my story isn't total BS, my ski buddies always give me a bad time for shaving my legs. Heck, plenty of women in that scene don't bother.

From what I can tell, the QR's they sent with my trainer must be made of lead and designed by AA rejects as I can think of no other explanation of how it would be possible to come up with such a soft and heavy QR that holds so poorly.

You can put enough pressure on the lever to bend it, yet the clamping force is mediocre. I tried using my other skewers with the trainer, but the trainer mechanism can't grab them properly.

Of course not - those things weigh a couple of ounces. You cant have all that weighing you down!

teterider

That's right - I believe he states that the lightweight skewers we all like to use with direct exposed concave washer don't have as much clamping force as the old standard enclosed cam Shimano or Campagnolo ones. However he doesn't provide force numbers or a study so it may have been his perception.

Just going to update what happened to my bike according from what our mechanic said. Apparently, I made the frame flex too much and it ripped out the skewers from the QR (which turns out they were not loose at all). The skewer that came with the Fuzion wheels was just crappy and was all bent up and stripped when he took it off. I also bent or somehow messed up the crank arm and the cassette a little bit. That's pretty much what I extrapolated from all his technical steel talk which I am not familiar with. I'll see if I can get a better description tomorrow when I pick it up. They were able to fix the frame for the most part, they bent the stays back into place, but I don't think I'll feel very comfortable riding it knowing it could happen again.

banerjek

This is far better than the technical description could possibly be

I can't imagine a frame flexing that much if things were properly set up unless there was a defect.

Also, I would be very leery of riding a bike that was just bent back in shape like it sounds like yours was. Even if someone with less massive guads were to ride it, the frame is likely to not be straight which could cause handling issues. I sure as hell wouldn't want to bomb down the side of a mountain on it.

zitter

They made sure the frame was completely straight, I watched them use the frame alignment gauge and frame straightener. Also, they said it might be possible to order an aluminum Orbea Aqua frame and swap out the components. The mechanic told me about how when he raced in the 80's that riders could change front rings by flexing the frame and not even using the shifter for the front derailleur, so I guess it is possible to flex a frame that much.

Sounds like it's perfectly good to ride. I'm not familiar with that particular frame, but unless you have specific reason to believe otherwise, it might be just as flexy. Frames flex more than many people realize.

zitter

I picked it up today, they wound up having to replace the cassette too since it was bent out of shape and the crank is a little warped but I'm getting a new one from my teammate anyway. I'm taking it out for a test ride later, I'll see how it holds up.
